Mathematics Question from JEE Main 2023 · 11 April, Shift 1

Let y=y(x)y = y(x) be a solution curve of the differential equation (1x2y2)dx=ydx+xdy(1 - x^2 y^2) \, dx = y \, dx + x \, dy If the line x=1x = 1 intersects the curve y=y(x)y = y(x) at y=2y = 2 and the line x=2x = 2 intersects the curve y=y(x)y = y(x) at y=αy = \alpha, then a value of α\alpha is:

  • A

    1+3e22(3e21)\frac{1 + 3e^2}{2(3e^{2} - 1)}

  • B

    13e22(3e2+1)\frac{1 - 3e^2}{2(3e^{2} + 1)}

  • C

    3e22(3e21)\frac{3e^2}{2(3e^{2} - 1)}

  • D

    3e22(3e2+1)\frac{3e^2}{2(3e^{2} + 1)}
